As shown, the recesses in the coupling member 16 are hemispherical and the recesses in the said parts are grooves 21. To provide a torque overload release, the recesses in the coupling member may be provided by one or a pair of helical grooves. At a predetermined torque the balls 20 force the coupling member axially against a spring until the balls circulate around an annular groove without transmitting any torque. The coupling is self-centring by means of a spring 27 which presses an edge 28 of the coupling member against an end wall of one of the said parts. The tool holder comprises locking balls 12 which are locked to engage a tap chuck by a spring biased sleeve 13. Lugs 15 positively drive the tap chuck. The shank part 1 comprises a shank 2 which is telescopically movable within a shell 3. A pair of springs 9 bias the shell 3 into a neutral position relative to the shank 2 from which it can be moved in either direction. Balls 10 provide torque drive while allowing axial relative movement.

Abstract: 1,122,725. Cathode-ray tube circuits; semiconductor switching circuits. INTERNATIONAL BUSINESS MACHINES CORP. 24 Oct., 1966 [26 Nov. 1965], No. 47517/66. Headings H3T and H4T. The deflection windings of an electromagnetically - deflected cathode-ray tube and to which a current of varying magnitude is supplied are shunted by a plurality of resistors the number of which is varied directly as the magnitude of the current. The invention is concerned with a display system in which the tube beam is deflected in straight lines between X, Y co-ordinate positions specified by digital signals from a computer, such signals being converted to analogue form to provide the deflection currents for the tube windings, the operation of the arrangement according to the invention resulting in a variation of the damping of the windings in accordance with the magnitude of the deflection currents so that the trace produced is of uniform velocity and therefore of constant intensity independently of the length of such trace. Thus, considering the X deflection circuit, the two halves X 1  X of the pushpull deflection windings which are shunted by respective adjustable resistors R R, are connected to one end of binary weighted resistors R/1, R/2 . . . R/8 and #R/1, #R/2 ... #R/8 the other ends of which are connected via diodes D1 . . . D8 to transistor switches 21 ... 28 which, when conductive, connect such ends to the potential +V which is the potential at the mid point of windings X 1 , X. Thus, in accordance with the state of the switches the latter are shunted by one or more of the resistors. The switches are operated by the outputs of a counter 30 the four stages of which are set by the four most significant digits in the " word " which specifies the larger of the X, Y co-ordinates of the end-point of the intended trace. This, which may be a ten " bit " word, is supplied from a computer to register 11 and after conversion to analogue form in D/A converter 12 is supplied via buffer amplifiers 14, 15 to the deflection windings. The counter thus sets the switches in accordance with the magnitude of the larger of the X and Y deflections (the Y circuitry 201 being similar to the X circuitry 20) and this setting is then reduced to zero by an oscillator 34 connected to the counter via AND gate 36 which is enabled by a signal from the computer at an appropriate time.

As shown, the piston 6 has an extension 18 which has a non-circular bore 20 in which a captive nut 22 is movable by means of the bolt 24 extending through a hole 26 in extension 18, and the member 28 is in the form of a deformable thrust washer situated between the head of bolt 24 and the end plate 14. For winding off, the bolt 24 is turned whereby the nut 22 is brought into engagement with a shoulder between bore 20 and hole 26 and the piston 6 is then moved rightwardly. The thrust washer 28 will deform under impact loading such as occurs when a sudden explosion of the spring 12 causes the piston 6 to travel through its full stroke and the shoulder collides with nut 22. In deforming the thrust washer 28 much of the impact energy is absorbed to avoid extensive damage to the brake unit 2. As illustrated the unit 2 is combined with a fluid-pressure actuated brake motor 4.
